ICD Procedure Codes

10.4 - ICD Procedure Codes (Rev. 3081, Issued: 09-26-14, Effective: Upon Implementation of ICD-10, Implementation: Upon Implementation of ICD-10) ICD procedure codes are required for inpatient hospital Part A claims only. Healthcare Common Procedure Code System (HCPCS) codes are used for reporting procedures on other claim types. Inpatient hospital claims require reporting the principal procedure if a significant procedure occurred during the hospitalization. For information of the selection of the principal procedure, see the Official ICD-10-PCS coding guidelines posted with the annual updates to ICD-10-PCS posted at http://www.cms.gov/Medicare/Coding/ICD10/index.html The principal procedure code and other procedure codes shown on the bill must be the full ICD-9-CM, Volume 3, or ICD-10-PCS procedure code, including all applicable digits, up to seven digits. Up to twenty four significant procedures other than the principal procedure may be reported.
